The amount of light pollution we have from cities is already more than necessary given that it covers makes most stars impossible to see.

I don't think a large quantity of small fake moons is gonna help with that.

    Last time a proposal like this made the rounds on the Internet stirring up consternation, the proposal was to use space mirrors to replace the street lighting for the Chinese city of Chengdu. It would have had no net effect on light pollution and would have reduced electricity consumption to boot.

    Bear in mind, this mirror focuses its light on a specific 5km-diameter patch of land. It won't be visible elsewhere.

    The visibility doesn't consider the massive glow that would appear to anyone seeing them outside their intended area of use due to reflections off dust and particles in the atmosphere. Light pollution goes far outside the area where cities are for the same reason, and having these in low earth orbit as a replacement for streetlights or as a spotlight would both have that happening.

    That's part of why experiments like this are done. Reflect Orbital would prefer that the spot be kept as tight as possible, they ultimately need to test out the technology to refine it.

    Almost everyone in this thread seems to be jumping straight from "their first prototype was approved for testing" to "therefore every plan of theirs is about to be immediately implemented." And the dopamine that comes from the ensuing rage and fear is making it hard to accept otherwise, it'd kill the buzz.
